My pleasure! That's exactly why I had to post it somewhere. I give away so many of these as gifts that people kept asking how it was made. This is such a great platform to point them to when they ask now instead of continually writing it up. :)

This was a great referral instructable while I was completing my exhaust fan replacement. I cannot thank you enough for your instruction! My older fan used a little large hole that the new one, so I did have to do some repair work with some sheetrock pieces, but the finished fans work great!

Thank you so much for posting this. I've been working out how to complete this task with both of our bathroom fans. It's going to take me a little time since I've never done anything quite like this before, but I'm determined to do it, as the bids I've received are outrageously expensive!
